Update - I called BMW customer service today and they informed me that the application for 4S in currently unavailable. They mentioned that they HOPE to have it in future months. Apparently, Black Berry is the only phone that works with all Office functions. Does anyone have a work around? It seems like there must be something out there for I Phone 5 according to what I have seen on this forum. I would just like to get texts and emails - does not have to have full functionality.
